In the preceding tabulation characters are selected which are independent of sex, 

 so far as possible, since in some species only one sex is known ; but the males of allied 

 species are sometimes most easily separated by the very well-marked differences in the 

 secondary sexual characters, viz. the tufts of hair on the hindwings and legs.
